AWK script for directory listing using GREP

Hi, All -

script1.awk contains the following script:

BEGIN {
printf "The following are directory files:"
"ls -l | grep '^d' | {print $0}"
printf "There were "NR" directories in this list."
}


When I run the script, Here is what I get:

$ awk -f script1.awk
The following are directory files:There were 0 directories in this list. $

When I run "ls -l | grep '^d'" by itself, I get 20 directories. How can I correct this script?
